2 different types of notification

It would be good to have 2 different types of notification, especially with the automated workflows:

• A main message - set and sent when the proof is created and when a new stage is automatically activated.
• A 1 time message - set and sent to individual, i.e. a personalised reminder. Currently, when a personalised reminder is sent, it replaces the main message and is then sent to the next stages approvers.
